The Siberian Husky is a breed of medium-sized working sled dog. The breed belongs to the Spitz genetic family. It is recognizable by its thickly furred double coat, erect triangular ears, and distinctive markings, and is smaller than the similar-looking Alaskan Malamute.
Siberian Huskies originated in the Russian Far East, where the breed was first developed by the Chukchi people for sled pulling and companionship. Other indigenous Siberian peoples in North Asia, such as the Koryak, Yukaghir, and Kamchadal, also breed them. It is an active, energetic, resilient breed, whose ancestors lived in the extremely cold and harsh environment of the Siberian Arctic. William Goosak, a Russian fur trader, introduced them to Nome, Alaska, during the Nome Gold Rush, initially as sled dogs to work the mining fields and for expeditions through otherwise impassable terrain. Today, the Siberian Husky is typically kept as a house pet, though they are still frequently used as sled dogs by competitive and recreational mushers.
Lineage and genetic structure
The Siberian Husky was originally developed by the Chukchi people of the Chukchi Peninsula in eastern Siberia.Fiszdon K, Czarkowska K. (2008). Social behaviours in Siberian huskies. Annals of Warsaw University of Life Sciences – SGGW. Anim Sci 45: 19–28. They were brought to Nome, Alaska in 1908 to serve as working sled dogs, and were eventually developed and used for sled dog racing.
In 2015, a DNA study indicated that the Siberian Husky, the Alaskan Malamute and the Alaskan husky share a close genetic relationship between each other and were related to Chukotka sled dogs from Siberia. They were separate to the two Inuit dogs, the Canadian Eskimo Dog and the Greenland Dog. In North America, the Siberian Husky and the Malamute both had maintained their Siberian lineage and had contributed significantly to the Alaskan husky, which was developed through crossing with European breeds. Siberian Huskies show a genetic affinity with historical East Siberian dogs and ancient Lake Baikal dogs, and can be traced to a lineage which is over 9,500 years old.
Population structure A 2024 genomic analysis of the Siberian Husky population examined 344 individual dogs including 280 Siberian Huskies and other reference individuals from separate populations, for the purpose of mapping population structure, identifying external breed admixture, and identifying COI and harmful health mutations. The study's analysis indicated that the Siberian Husky gene pool has emerged into four genetically distinct populations: Show Siberian Huskies, Pet Siberian Huskies, Racing Siberian Huskies and Seppala Siberian Sleddogs. Around half of modern Siberian Huskies used in sleddog racing (the Racing and Seppala groups) were found to have genetic admixture from outside the Arctic dog lineage (European breeds) consistent with that mapped in the Alaskan Husky, though only the Racing group contained several individuals which mapped outside the 99% confidence interval for the Siberian genome. This suggests gene flow from unrelated breeds outside the purebred studbook has been introduced at various points in history, possibly for improvement of athletic performance in changing climates and racing conditions. The Show and Seppala populations had the smallest effective population size of the four. The Pet and Seppala populations showed the highest number of harmful alleles, and the Show population had the lowest level of heterozygosity, indicating a higher level of relatedness within that population, and thus less genetic diversity, likely due to sustained long-term inbreeding.
Several Arctic dog breeds, including the Siberian Husky, show a significant genetic closeness with the now-extinct Taimyr wolf of North Asia due to admixture. These breeds are associated with high latitudes – the Siberian Husky and Greenland Dog, also associated with arctic human populations and to a lesser extent, the Shar-Pei and Finnish Spitz. There is data to indicate admixture of between 1 and 3% between the Taymyr wolf population and the ancestral dog population of these four high-latitude breeds. This introgression could have provided early dogs living in high latitudes with phenotypic variation beneficial for adaption to a new and challenging environment. It also indicates the ancestry of present-day dog breeds descends from more than one region.
Description
Coat
A Siberian Husky has a double coat that is thicker than that of most other dog breeds. It has two layers: a dense, finely wavy undercoat and a longer topcoat of thicker, straight guard hairs."Get to Know the Siberian Husky", 'The American Kennel Club', Retrieved 29 May 2014 It protects the dogs effectively against harsh Arctic winters, and also reflects heat in the summer. It is able to withstand temperatures as low as . The undercoat is often absent during shedding. Their thick coats require weekly grooming. An excessively long coat, sometimes referred to as a "wooly" or "woolie" coat, is considered a fault by the breed's standard as it lacks the thicker protection of the standard coat's guard hairs, obscures the dog's clear-cut outline, causes quicker overheating during serious harness work, and becomes easily matted and encrusted with snow and ice.
Siberian Huskies come in a variety of colors and patterns, often with white paws and legs, facial markings, and tail tip. Example coat colors are black and white, copper-red and white, grey and white, pure white, and the rare "agouti" coat, though many individuals have blondish or piebald spotting. Some other individuals also have the "saddle back" pattern, in which black-tipped guard hairs are restricted to the saddle area while the head, haunches and shoulders are either light red or white. Striking masks, spectacles, and other facial markings occur in wide variety. All coat colors from black to pure white are allowed. Merle coat patterns are not permitted by the American Kennel Club (AKC) and The Kennel Club (KC). This pattern is often associated with health issues and impure breeding.
Eyes
The American Kennel Club describes the Siberian Husky's eyes as "an almond shape, moderately spaced and set slightly obliquely". The AKC breed standard is that eyes may be brown, blue or black; one of each or particoloured are acceptable (complete is heterochromia). These eye-color combinations are considered acceptable by the American Kennel Club. The parti-color does not affect the vision of the dog.
Nose Show-quality dogs are preferred to have neither pointed nor square noses. The nose is black in gray dogs, tan in black dogs, liver in copper-colored dogs, and may be light tan in white dogs. In some instances, Siberian Huskies can exhibit what is called "snow nose" or "winter nose". This condition is called hypopigmentation in animals. "Snow nose" is acceptable in the show ring.
Tail Siberian Husky tails are heavily furred; these dogs will often curl up with their tails over their faces and noses in order to provide additional warmth. When curled up to sleep the Siberian Husky will cover its nose for warmth, often referred to as the "Siberian Swirl". The AKC recommends the tail should be expressive, held low when the dog is relaxed, and curved upward in a "sickle" shape when excited or interested in something.
Size The breed standard indicates that the males of the breed are ideally between tall at the withers and weighing between . Females are smaller, growing to between tall at the withers and weighing between . The people of Nome referred to Siberian Huskies as "Siberian Rats" due to their size of , versus the Alaskan Malamute's size of .
Behavior The Husky usually howls instead of barking. They are known to mimic high-frequency noises, such as ambulance sirens, as well as human speech. They have been described as escape artists, which can include digging under, chewing through, or even jumping over fences.
The ASPCA classifies the breed as good with children. It also states they exhibit high energy indoors, have special exercise needs, and may be destructive "without proper care".
A fence is recommended for this breed as a pet, although some have been known to overcome fences as high as . Electric pet fencing may not be effective. They need the frequent companionship of people and other dogs, and their need to feel as part of a pack is very strong.
The character of the Siberian Husky is friendly and gentle. A study found an association with a gene in the breed and impulsivity, inattention, and high activity.
Siberian Huskies were ranked 77th out of 138 compared breeds for their intelligence by canine psychologist Stanley Coren. However, the rankings in Coren's published work utilized only one of three defined forms of dog intelligence, "Working and Obedience Intelligence", which focused on trainability—a dog's ability to follow direction and commands in a direct context, specifically by trial judges in a controlled course setting.
Health A 2024 UK study found a life expectancy of 11.9 years for the breed compared to an average of 12.7 for purebreeds and 12 for crossbreeds. Health issues in the breed are mainly genetic, such as seizures and defects of the eye (juvenile cataracts, corneal dystrophy, canine glaucoma and progressive retinal atrophy) and congenital laryngeal paralysis. Hip dysplasia is not often found in this breed; however, as with many medium or larger-sized canines, it can occur. The Orthopedic Foundation for Animals currently has the Siberian Husky ranked 155th out of a possible 160 breeds at risk for hip dysplasia, with only two percent of tested Siberian Huskies showing dysplasia.
Siberian Huskies used for sled racing may also be prone to other ailments, such as gastric disease, bronchitis or bronchopulmonary ailments ("ski asthma"), and gastric erosions or ulcerations.
The Siberian Husky is one of the more commonly affected breeds for X-linked progressive retinal atrophy. The condition is caused by a mutation in the RPGR gene in the breed.
Modern Siberian Huskies registered in the US are almost entirely the descendants of the 1930 Siberia imports and of Leonhard Seppala's dogs, particularly Togo. The limited number of registered foundational dogs has led to some discussion about their vulnerability to the founder effect.
History
Prehistoric (prior to 1890s) The Chukotka Sled Dog is considered the progenitor to the Siberian Husky. Developed by the Chukchi people of Russia, Chukotka sled dog teams have been used since prehistoric times to pulls sleds in harsh conditions, such as hunting sea mammals on oceanic pack ice.
Origination of name and split from Chukotka Sled Dogs (1890s–1930s) From the 1890s to the 1930s, sled dogs from northeast Siberia and especially Chukotka sled dogs were actively imported in vast numbers to Alaska, to transport gold miners to the Yukon, first as part of the Klondike Gold Rush, then later the "All-Alaska Sweepstakes", a 408-mile (657-km) distance dog sled race from Nome, to Candle, and back. At this time, "Esquimaux" or "Eskimo" was a common pejorative term for native Arctic inhabitants with many dialectal permutations including Uskee, Uskimay and Huskemaw. Thus dogs used by Arctic people were the dogs of the Huskies, the Huskie's dogs, and eventually simply the husky dogs. Canadian and American settlers, not well-versed on Russian geography, would distinguish the Chukotka imports by referring to them as Siberian Huskies as Chukotka is part of Siberia.
Smaller, faster and more enduring than the 100- to 120-pound (45- to 54-kg) freighting dogs then in general use, they immediately dominated the Sweepstakes race. Leonhard Seppala, the foremost breeder of Siberian sled dogs of the time, participated in competitions from 1909 to the mid-1920s with a number of championships to his name.
